It's probably safe to say that the New York Yankees and the Boston Red Sox don't particularly care for one another.

It's probably also safe to say that their respective fans bases don't either.

Well, how about adding fuel to the fire?

Okay, so this isn't that big of a deal, but we do have a Red Sox fan snatching a ball that was tossed in the direction of a Yankees fan, and then giving it to another fan of the Red Sox.

The staff did make him return it. Why? Because they were at Yankee Stadium.

That, and because the guy was hollering for the ball, and because it was thrown to him. It was the right thing to do.
